Useless Telkom

Telkom has the worst customer service, my dad's adsl line has been down since February, Telkom says it was a system error and their system deleted the adsl line. Since Feb I've called almost everyday sent from this department to that no one knows how to solve it!!! This is becoming absolutely ridiculous how long does it take to reactivate a line??? And yet we are still billed for it. I've written about it on Facebook as well and got told in my inbox that the issue has been escalated yet still nothing is done. Come on Telkom this is ridiculous. And another issue is that my dad requested an upgrade on his line speed from 2 mbps to 10, from Dec last year, it's still on pending and yet we are billed for a 10 Meg line. I think it's now time to go the legal route as nothing seems to help anymore ????. Telkom Ref no **********
